- Fix data frames transmission via POWER_STATUS register setup -
it seems to be set by MACID_CONFIG firmware command, which was broken*
in r290439 and later disabled in r307529.
We can re-enable it later if / when firmware rate adaptation will be
ready; however, this step will be required anyway - for firmware-less
builds.
- Force RTS / CTS protection frame rate to CCK1 (this rate works fine
without any additional setup; no better workaround is known yet).
The problem was not observed on the channel 1 or with CCK1 rate enforced
('ifconfig wlan0 ucastrate 1' for 11 b/g; not possible for 11n networks
due to ifconfig(8) bug).
* I'm not sure if it works before r290439 because - AFAIR - I never seen
firmware rate adaptation working for 10-STABLE urtwn(4)
(It needs EN_BCN bit set and RSSI updates at least).
Tested with RTL8188CUS in STA mode
(in regular mode and with disabled MRR - DARFRC*8 is set to 0)

Rate tables have this bit set to indicate minimal set of basic rates;
however, it overlappes with MCS bit, so rate2ridx() will treat them as
an 11n rate.
Due to the current rates setup the issue can be reproduced only
in 5GHz band with 11n / protection enabled.
Tested with RTL8821AU, HOSTAP mode.

The code is similar to the one for RTL8188E* and probably
should be shared with RTL8188CE (needs to be tested).
Checked with RTL8188CUS, STA mode.
MFC after: 5 days
Tx power values can easily fit into uint8_t + only 8 bits are written
to registers; values may overflow only in case if ROM contains
malformed data (but limit is checked anyway).
Tested with RTL8188CUS, dev.rtwn.1.debug=0x2000 (no changes).
for the rtl8188eu chipset
- Rename struct r92c_rom member names: s/channel_plan/reserved5/,
s/xtal_calib/channel_plan to be compliant with definitions of the efuse
in vendor hal_pg.h
Omit unused rates while initializing / dumping Tx power values.
They were not accessed anywhere (except for debugging), so this is
(mostly) no-op.
Tested with
* RTL8188EU, STA mode.
* RTL8812AU, STA mode.

use r92c_init_rf() rather than r92c_init_rf_common() when sc_init_rf()
callback is invoked.
While here, constantly use RF chain instead of RF path in comment.

- Increase Rx buffer size from MCLBYTES to MJUMPAGESIZE.
- Provide an additional defragmentation routine for frames larger
than MCLBYTES; that is required by A-MSDU / Atheros Fast-Frames
support to work with current Tx path implementation.
Enabled features list for RTL8188CE:
- Atheros Fast-Frames;
- A-MPDU (Tx / Rx);
- A-MSDU (Tx / Rx; 4k only);
- Short Guard Interval.
Tested with:
- RTL8188CE (STA+AP) + RTL8821AU (STA).
- RTL8188CE (STA) + RTL8188CUS (AP).
Relnotes: yes
NOTE: some multi-vap configurations (e.g., STA+IBSS) are not stable;
that will be fixed later.
Tested with:
- RTL8188CE, STA + AP mode;
- RTL8188CE, IBSS mode;
- RTL8188CUS, IBSS mode;
- RTL8188EU, IBSS mode.

All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
* for RTL8821AU: 2 VAPs at the same time;
* other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
* bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
* common (if_rtwn*)
* chip-specific (rtl*/*)
- various other bugfixes.
Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn rtwnfw -> rtwn rtwn_pci rtwnfw
Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.
